More than $75,000 in federal student aid may have been improperly awarded at East Carolina University because of employee error, an internal audit has found. According to The Daily Reflector, a local newspaper, auditors found that financial-aid administrators had used their “professional judgment” to award the money without double-checking the students’ personal data or filing adequate documents.

Under university policy, administrators must obtain and file proper documentation before using their professional-judgment authority.

The audit also cites several cases in which student files lacked documents to support the awarding of aid. Five of 22 student records sampled had none of the required documents to prove the students’ eligibility, according to the newspaper.

News of the audit came a month after an investigator from the U.S. Department of Education’s office of the inspector general spent three days reviewing student-aid files at the university. It’s unclear why the office reviewed those records or what it concluded, the newspaper reported.
